. METALLIC BARREL.

Specification of Letters Patent. Application filed August 5, 1912. Serial No. 713,337.

Patented Sept. 16, 1913..

To all whom it may Be it known that we, Gnoncn J. CLARK and HERBERT CURTLAND, citizens of the United States of America, residing at Defiance, in the county of Defiance and -State of-Ohio, have invented certain new and useful Imrovements in Metallic Barrels, of which the chewing is a specification.

This invention relates to bai'relsand has especial reference to metallic barrelsm The invention has for its object to provide an improved metal barrel preferably formed of steel and constructed with two sections, so that theb'arrel is .formed with I only one seam.

The invention further has for its objectto provide a steel barrel constructed in two sections secured together so as to provide but a single joint and render the barreHight, strong and durable.

The accompanying drawing shows a metal barrel constructed-1n accordance with this a invention the figure being a view partly in side elevation and partly in section. I

In carrying out the invention the barrel is constructed with two; cylindrical sections 1, preferably of steel,-and pressed so as to form a chine 2 at bne end of each sect-ion, and a head 3. The edge of the open end of each section 1 is bent in so as to form an an nular flange 4, and in the construction of the barrel the sections 1 are placed together with the flanges 4 of their meeting, open ends abutting together. To reinforce and strengthen the seam formed by the abutting flanges 4 a metallic annular band ring 5 is located within the barrel, and is'formed with an annular groove 6, in which the abutting flanges 4 are adapted to be seated, the open flanged ends of the sections 1 being slipped over the metal band 5 into the position shown. The joint ,formed b the abutting flanges 4'resting in the arm ar groove 6 is welded or brazed. The groove formed by the flanges 4 is thereby filled with suitable metal -11 so as to form a smooth surfaceon the exterior of the seam or joint' formed by said flanges Before the sectionsl are secured together, as hereinbefore described, the chlnes 2 may be filled witha suitable reinforcing metal, such "as a metal rod 7. One

of the heads 3'is provided with a suitable bung-hole 8, which can be closed by a plug, or, as here shown, by a suitable cap 9 mountedover said bung-hole.

' It will be seen that a barrel constructed as hereinbefore described, with only one seam, will be strong and durable, and that leakage is avoided. By forming the half sections with a chine and head in one piece, a strong, durable barrel can be economically manufactured and will be stronger than a barrel formed in several pieces.

Having described the invention, we claim:

A metallic barrel consisting oftwo abutting tub-like sections, each formed in one piece with a chine and head and at its abutting end with an inturned annular flange, an annular metallic band lying within the barrel and provided witha peripheral groove in which. said annular flanges lie and abut, the inturning of said flanges forming a pcripheraLgroove about the barrel and a: filling of brazing material the last named peripheral groove which brazes'said flanges and said band together and fills said groove to render theouter face. of the barrel flush and smooth. In testimony whereof we afiix our signatures in presence oftwo witnesses.
